    Laser remelting on the surface of Cr12 steel was performed by CO2 Laser. Microstructure of the laser remelting layer is studied by optical microscopy, SEM. Wear resistance of Cr12 steel before and after laser surface remelting is studied. The reasons for enhancing wear resistance is discussed. The experimental results show that the super-refined microstructure with dendritic A′ and interdendritically laminal transformed ledeburite (A′+(Cr?Fe)7C3) were formed in the remelting layer. Super-refined microstructure and plenty of austenite after laser surface remelting and formation of dislocation cluster during wear reinforce wear resistance。
